Calculating S-Parameters — Lesson 3

In this lesson we will work through the calculation of S-parameters for a simple example two-port network. This course was created for Ansys Innovation Courses by Dr. Kathryn Leigh Smith, assistant professor, UNC-Charlotte, in partnership with Ansys.

This is honestly one of the best series and explanations I have listened to and watched. You have great ability at making seemingly complex topics lucid and comprehensible. I look forward to more in your series on electromagnetics and I think you have some great potential at really striking it big with these because they're absolutely top notch.

I think this is one of the most useful vídeos I’ve seen during my career

[enricodona]

extremely clear work-through of the problem. You are an outstanding teacher, thank you!

[danielmelendrez]

Hey, Dr. Leigh. Thank you very much for this quality content. We need more of it! Very useful when you are a bit rusty on these topics. Cheerio!

[Allez_Malherbe_]

Very good work. Your explanations are clear and concise. These videos will please to engineers. It's difficult to explain the S parameters to electronic engineers.

[eggertgudmundsson]

Thank you! I needed a refresher and stumbled upon your videos! Concise and clear. Really well done! Thank's again!

[MIBA]

I have completed my RF module examination and managed to get A- thanks to you prof..🙏🙏

[thiru]

😘😘😘you are teaching better than my professor 🤗😊

[Daniel-irki]

This was super helpful! You're awesome!

[antonivanov]

not exactly get the “simple circuit analysis”, as I understand, you use KVL, where you find the current looking from port 1: which is V1 divided by Z1 + Z2||(Z3+Z0), and from port 2: V2 divided by Z2||(Z3+Z0), and I have no idea, why do you multiply the right part of this 2:03 equation by Z0/(Z3+Z0)

[charliebe.]

Z0 depends on Z1, Z2 and Z3. To be matched: Z0 (the one on the right hand side) has to be Z3 + Z2 || Z1, provided the source is an ideal voltage source. Or am I wrong?

[sebastianfraga]

How can I calculate the S parameters of a quarter wave transformer?

[Confusion-ddyx]

what is the characteristic impedance of a port?
